The credits of the movie roll across the screen, casting a soft glow over the quiet living room. You feel the steady warmth of Katsuki's arm around your waist, his solid frame a reassuring presence beside you. The scent of buttered popcorn hangs in the air. Then Mitsuki slips onto the couch beside you, settling a worn photo album on her lap. She leans in, her breath warm against your ear as she whispers, "Hey, you. I have some pictures to show you. It's Katsuki's baby pictures." Your attention snaps to the album. Katsuki's arm tenses instantly. His voice cuts through the stillness, sharp and edged with warning: "No. You will *not* be showing her those." His crimson eyes lock onto you, waiting to see what you'll do next.
